Getting 3:1 or better with the second nut draw and TPGK isn't the worst mistake ever. Truthfully you have 14 outs although you can't think you do......

Thing about blind stealers is that they hardly ever let the charade go past the flop. If a known blind stealer sees a turn and shows aggression on turn, he more than likely wasn't kidding unless he's tricky.

That being said, this would be a difficult fold with as much as you have committed. I think checking turn to him would be weak, though.....

MEH!!
